Gnarled old man with his gnarled old stick

There has been a gnarled old man with a gnarled old stick that has frequented my dreams lately.  Sometimes he is so terrifying that I cry out in the night, and sometimes he is intriguing as if I'm supposed to learn something from his infinite gnarled wisdom.  Whatever it is I decided I would try to describe him.  It's going to be a lot of guess work as many details get lost in my sleep but we'll see.

Age: Old/Ancient

Height: 5'8" stooped over his stick (maybe... It's a supposition). 

Posture:  Hunched over with his shoulder blades nearly parallel to the ground.  Head erect with chin parallel to the ground.

Hair: Wispy and white with strands of silver.  Long thin curly beard of the same color.

Face: Old and gnarled or sometimes he is half gnarled and half something else (young and wicked, submerged in shadows, young and sorrowful/full of pity).  Deep wrinkles carved throughout his face.  Wrinkles between the eyebrows as if he is in a constant scowl.

Apparel: Trudges about on a twisted wooden stick.  Carries a shoulder bag worn diagonally across his torso ending near his hip.

That's pretty much all I've got.  Even though at times he sends me into a terrorized panic I want to see him more.  I want to figure out what his story is.  I want to hear what he has to say, and I really want to know why he gives me looks of pity.  I just hope he doesn't come with his wicked face.
